BUILDING COLUMN.

Application led September 13, 1921,*Seria1 No. 500,385. RenewedSeptember 25, 1923.

To all wlwm t may concem:

Be it known that I, JOHN LALLY, a citizenk of the United States, and aresident of Boston, Suffolk County, Massachusetts, have 5 inventedcertain new and useful Improvements in Building Columns, of which thefollowing is a specification.

y invention relates to columns of the reinforced concrete type and it ismy obproduce a column provided with tie plates for attaching the floorbeams in which the tie plates will be solidly attached one to anotherand to the column. Another object is to provide the tie plates withdevices within the column which will increase the vertical resistance ofthe tie plate and resist any tendency to tip under load.

In the accompanying drawing Fig. 1 is a front, sectional view of myimproved column; F ig. 2 a sectional view of the structure of Fig. 1 onthe line 2 2- thereof with the plastic filling omitted for clearness ofillustration; Fig. 3 a sectional view of a modified form of tie plateconstruction; and Fig. 4 a view of a further modification.

The column comprises a casing 1, generally of steel tubing or iron pipe,provided with slots 2, 2 at the points where the tie plates are to beattached. In the forms shown in Figs. 1, 2 and 3 a long tie plate 3extends through opposed slots and short tie plates 4 and 5 extendthrough the remaining slots and abut against the tie plate 3 within thecasing. The tie plates are perforated within the casing and U-shapedclip 6, 6 are hooked through perforations in the plates 4 and 5 withtheir legs extending through perforations in the tie plate 3 so that thetie plates may be drawn solidly together by drawing up on the nuts onthe threaded ends of the clips. y The casing is then lilled with plasticmaterial, such as concrete, thereby increasing the strength and furtheruniting the parts.

In order that the vertical resistance of the tie plates may be increasedand their liability to tip under load may be prevented thrust pins 7 maybe inserted in perforaplates within the casing and spaced from the innerwall thereof, which, when imbedded in the plastic filling, will greatlyincrease the vertical resistance and tendency 'for the plates to tip inthe slots.

As shown in Fig. 3 a perforated reinforcing plate 8 may be secured tothe bottom edges of the tie plates by clips 9, 9 engagin perforations inthe tie plates 3 and and the reinforcing plate 8. The casing is thenfilled with plastic material from both ends and the tie plates, andthrust pins if used, are solidly held by being embedded in the plasticmaterial.

If desired the tie plates may be welded to the slots in the casing toincrease the weight bearing capacity.

he columns thus produced arev characterized by the absence of protrudingbrackets to carry the beams as the tie plates lie on the side of thevbeams and are concealed in the floor itself leaving -the column ofuniform size from oor to ceiling.

In Fig. 4 I have shown how a single short tie plate 5"may be attached toa cross plate 3 by clip 6 if but one beam is to be carried.

claim:

l. A building column comprising a casing provided with slots, aerforated plate extending through opposedp slots, a perforated tie plateextending through the other slot and abutting the first plate within thecasing, a clip passing through perforations in both plates binding thetwo together and a filling of plasticmaterial within the casingembedding the inner ends of the plates and clip.

2. A building column comprising a. casing provided with slots, aperforated long tie plate extending through opposed slots, shortperforated tie plates extending through the other slots with their endsabutting the long tie plate within the casing, clips passing through theperforations in the plates binding them together and a filling ofplastic material within the casing embedding the inner ends of theplates and the y clip.

3. A building column comprising a casing provided with slots, perforatedtie plates extending through the slots and lying partly within andpartly without the casing, thrust pins in the plate perforations awayfrom the inner wall of the casing and a filling of plastic materialwithin the casreinforcing plate, clips ing embedding the inner ends thetie plates and thrust pms.

4. A building cplumn comprising a casing provided with slots, perforatedtie 5 plates extending through the slots and secured together within thecasing, a. reinforcing plate within the casing secured to the loweredges of the tie plates and a plastic lling within the casing embeddingthe tie plates and reinforcing plate.

In testimony whereof I have hereunto subscribed my name.

JOHN LALLY.
